Okay so may probably know that the game Minecraft has now been added to the xbox 360. Now I am trying to download a map on my usb, but when I plug the usb with the map on it into the xbox it says everything will be "erased". A friend was mentioning something about a program called Horizon??? If you have any information please comment and if you know the link for Horizon, please leave it because I don't know which is the right one.
